Terminates the last protected function called and returns message as the error message. Function error never returns.
error (message [, level])
Parameters[ | ]
Arguments[ | ]
- message
- string - The error message to propagate.
- level
- integer - Usually, error adds some information about the error position at the beginning of the message. The level argument specifies how to get the error position. With level 1 (the default), the error position is where the error function was called. Level 2 points the error to where the function that called error was called; and so on. Passing a level 0 avoids the addition of error position information to the message.
Returns[ | ]
- none

error("Argument for function foo cannot be zero",2)

return 55378008/x
